ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

The first calculation of energy exchange between electrons and the radiation field by inverse Compton and Compton recoil was reported by Hurwitz in Los Alamos Reports LA-301 (1945) and LA-553 (1946). These reports have not been generally known; even in 1950, Bethe called attention to their neglect. Yet, they predated Kompaneets’s widely cited 1957 paper and original 1950 report. “Comptonization” is important in many astronomical objects as well as in fusion energy. I make a very brief comparison with Kompaneets’s work and present Hurwitz’s reports as appendixes.
